USE-2 indoors?

System
Posts: 2,511 admin
Hey all,
What is your opinion of 10AWG Type USE-2 run in EMT off of the roof(array), directly to the inverter located in the basement?
Would this really be considered "interior wiring" (338.12)? It seems that would be the letter of the code, but is it also the intent to prohibit this? Why the need to transition to THWN-2 (or equivalent)?
I can see not being able to use USE to say, feed your range as single conductors run through the studs!!, but was 338 written to take PV source circuits into account?
Thanks for the input

Re: USE-2 indoors?
I may have just found the answer to my own question in an old J.Wiles article.
I always wondereed what that VW-1 label on the USE-2 was!:roll:
Evidently the USE wire I've been using all these years was also RHW-2(I checked) and has the flame retardent needed for indoor use.
What do you think of that? -

you can use use-2 for interior runs in emt if it also marked rhw-2
